WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 291,549, dated January 8, 1884.

Application filed June 23, 1883. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE A. THOMPSON, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Window-Screen, of which the following specification is a full, clear, and exact description.

This invention relates to that class of window-screens which are automatically raised and lowered with the lower sash; and the intion of awindow-frame with aboX, screen, and rod having knobs, and with split guide-tubes which receive said knobs, all as hereinafter more fully described; also, in the details of improvement hereinafter more fully pointed out.

In the accompanying sheets of drawings, Figure 1, Sheet 1, is a perspective view of lower part of a window provided with my improvement. Fig. 2, Sheet 2, is a vertical transverse section of'the same. Fig. 3, Sheet 2, is a detail view of the screen and its attachments; and Fig. 4, Sheet 2, a detail view of one of the guide-tubes.

Similar letters of reference indicate corresponding parts in all the figures.

The letter A represents a window-frame, a being the upper and b the lower sash. Upon the window-ledge and below the upper sash, a, is placed a, box, 0, which contains a springroller, d. Around this spring-roller is wound the screen or netting e. This netting is attached at one end to said spring-roller, while its other end passes out of a slot in the box 0,

as seen in Fig. 2. The upper end of netting e is fastened to a rod, f, said rod having knobs g at its ends,which enter and slide in vertical split tubes h, attached to the parting-strips between the window-sashes. The rod f is also provided with eyes i i, which are adapted to be slipped over buttons j, (dotted in Fig. 1,) affixed to the lower sash, b. A handle may likewise be attached to rod f, as shown in Fig. 1.

The operation is as follows: The upper edge of the screen is attached to sash b by means of eyes i and buttons j and on raising the sash the screen will be raised with it. On lowering the sash the spring-roller d will draw the slack of the screen into the box 0, thus keeping the screen taut at any position of the sash. If it is desired to clear the window of the screen, the latter is unhooked from sash b, and will be drawnentirely into the boX 0.

I claim as my invention 1. The combination of window-frame A with box 0, spring-roller (1, screen a, and rod f, having knobs g, and with the split guide-tubes h, which receive said knobs, substantially as herein shown and described.

2. The combination of window-frame A with box 0, spring-roller d, screen 6, rod f, having knobs g and eyes i, and with the guide-tubes h, and buttons j on the lower sash, substantially as specified.

GEORGE A. THOMPSON.
